PATENTEDJUN 17 I975 SHEET 2 FIG.6 FIG? FLASHLIGHT DEVICE This is a continuation of application Ser. No. 208,866 filed Dec. 16, 1971, now abandoned.

BACKGROUND OF THE INVENTION The present invention relates generally to flashlight devices, and more particularly relates to an improved construction for a flashlight device of the type for use with one or more battery cells which includes a single body construction or a multiple body construction in cluding a plurality of interchangeable barrel members for increasing the battery cell capacity and length of the device. The flashlight device of the present invention has particular application for police, fire use or the like.

Heretofore, various types of flashlight devices have been provided which are generally of a conventional unitary or one-piece construction which are made in various sizes, generally, such prior flashlights have been of a rather flimsy and inexpensive construction with limited flexibility in use by reason of their being of a given size. Accordingly, such prior flashlights in many cases were either too bulky and space consuming for compact carrying and/or storage, such as on the person of the user, or are of such small sizes so as to be ineffective as a working tool or protective weapon as in the case of police and fire applications. Further, since such prior flashlights were of a unitary construction limitations were placed on the battery cell carrying capacity of the light and hence, such devices had limited application or it was necessary to have two or more flashlights for various uses.

As best seen in FIGS. 1, 2, 5 and 6. the main body member 4 includes an elongated knurled member 10 of a cylindrical construction which is made integral with an enlarged head member 12. The barrel member 10 is of a hollow construction adapted to receive a single battery cell and includes an elongated cylindrical passageway 14 extending therethrough and through the head member 12. As shown, the member I0 is internally threaded, as at 16, adjacent its end adapted for threadable connection to an end cap assembly or to another one of the barrel members 6 or 8, for example. The member 10 is provided with an opening 18 adapted to receive a switch assembly 20 (FIG. 2) which coacts with a conductive member 22, such as a copper slide, for actuating a light assembly 24, as known in the art.

The head member I2 includes a forwardly facing annular portion 26 which has a greater diameter as compared to that of the barrel 10. The annular portion 26 is joined to the barrel 10 by an inclined ramp-like portion 28 which tapers downwardly and inwardly toward the barrel 10. As shown, the length of the head member 12 including the surfaces 26 and 28 is approximately one-third the length of the body member 4 or approximately one-half the length of the barrel I0 to provide the compact construction shown. Accordingly, the

axial length ofthe barrel I is less than twice the length of its diameter. For example, the barrel l0 may have a length of 2% inches while the outside diameter may be I 4 inches. Preferably, the surface 28 may have an in clination of approximately [5 and with the diameter of the surface portion 26 being approximately 2% inches.

As best seen in FIG. 5, a forwardly extending shank- Iike member 30 is made integral with and projects axially outwardly from the head member 12. The member 30 is externally threaded. as at 32, for threaded attachment to a face cap member 34 (FIG. 2). The member 30 is provided with an internal chamfer. as at 36 to facilitate installation of the light assembly 24. The member 30 preferably has an OD. approximately equal to that of the barrel member 10. As seen in FIG. 6, the lengthwise extending slot 38 is provided to receive the slide bar 22, as shown in FIG. 2.

In the form shown, the light assembly 24 includes a lens 40. a reflector 42, a bulb retainer 44, a bulb 46, and a shock ring 48 for bearing engagement with a battery cell (not shown] as known in the art.

The face cap member 34 includes a central opening defined by an internal chamfer surface. as at 52, (FIG. 2) of ap proximately 45. Moreover. the inclination of the chamfer surface 52 is generally coincident with the in clination of the reflector 42 so as to maximize the light reflection characteristics of the device. Preferably, a rubber gasket 54 is disposed in encompassing relation around the outer peripheral end of the reflector 42 and is disposed in the space between the confronting inte rior surfaces of the face cap member 34 and that of the shank member 30 to provide a seal against contaminants, moisture and the like from entering the device.

In the form shown, the barrel member 6 is ofan elongated cylindrical construction which is externally threaded. as at 60 at one end adapted for threaded connection to the interior threads 16 of the barrel member 10. The opposite end of the barrel 6 is internally threaded as at 62. for threaded connection to the end or rear barrel member 8. Accordingly. the rear barrel member 8 is externally threaded. as at 64 for threaded attachment to the internal threads 63 of the barrel member 6 and is internally threaded, as at 66, for threaded attachment to an end cap assembly 70, as best seen in FIG. 2.

As best seen in FIG. 2 and 7, the cap end assembly 70 includes a base member 72 of generally flat construction having an integral outwardly extending shank-like member 74 which is externally threaded, as at 76, for threaded engagement with the internal threads 16 of the main body member 4, or with the threads 62 of the barrel member 6 or with the threads 66 of the barrel member 8 in interchangeable relation, as desired. The base member 72 has a generally centrally disposed aperture which is internally threaded, as at 78, for threaded attachment to a fastener element 80 (FIG. 8) in the installed position thereof. The base 72 and shank 76 members together provide a centrally disposed recess 82 which concentrically communicates with another recess 84 so as to define an annular shoulder 86 which provides a seat for mounting a resilient retainer spring 88 (FIG. 2) for holding the battery cells (not shown) in the installed position within the device. Accordingly. the cap assembly provides a compartmentlike structure which provides a storage area while at the same time providing an end closure for the device.

As best seen in FIGS. 2 and 8. the fastener element includes an annular base or collar portion 90 from which extends a pilot-like end 92 which is threaded, as at 94, for coacting threading engagement with the internal threads 78 provided on the cap assembly 70. Moreover. as the threads 94 are turned into place with the threads 78, the base 90 is drawn down into tight abutting engagement with the confronting surface of the base 72 for holding the fastener in the installed position. An elongated stub shank 96 extends outwardly from the base 90 and has a transverse aperture 98 extending therethrough adapted to receive a hand carrying or gripping element 100 (FIG. 2) such as a thong or the like for carrying or mounting the device.

In a typical example, the main body member 4 and the interchangeable barrel members 6 and 8 may be employed so as to carry one, two, three or four dry cell batteries, as desired. By way ofexample. the number of cell combinations together with the weight and overall length of the respective combinations are set forth in the following table.
